"The best I could reach now on 160m is
- SWR: 1:1.29 (Rs=40.4 Ohms, Xs=-5.4 Ohms)
vs. in 2019:
- SWR: 1:1.16 (Rs=43.2 Ohms, Xs=-1.6 Ohms)"


If I can get those matches on a *transmitting* antenna, I am very satisfied!

I built three 2-wire beverages using W0BTU's design (single coax) and 
measured best SWR around 1.5:1 and didn't give it a second thought. They are 
all 269 m long, using 2.5 mm galvanised high-tensile fencing wire. They 
work!
